  • Patent number: 12525022
    Abstract: A method for detecting a trailer presence includes identifying a region of interest within a video feed from one or more cameras secured to a vehicle. The video feed depicts a scene having a first pixel area, and the region of interest corresponds to a portion of the scene having a second pixel area that is less than the first pixel area.

  • Patent number: 12511913
    Abstract: A method of checking wing position in a CMS includes performing a calibration of a wing position supporting a camera relative to a vehicle to provide a desired field of view by capturing multiple images at different lighting conditions, extracting and storing a reference feature from each of the multiple images, triggering a wing position check, capturing a current image from the camera having a current position of the reference feature; sensing a current lighting condition at which the current image is captured, determining that one of the different lighting conditions is more similar to the current lighting condition, comparing the current position of the reference feature to the stored reference feature from the one of the multiple images generated under the one of the different lighting conditions, and outputting a result of the wing position check if a difference from the comparing step exceeds a threshold value.

  • Patent number: 12269544
    Abstract: A method for determining a trailer detection parameter of a trailer including receiving an image from at least one camera at a controller. The at least one camera defines a field of view including at least a portion of a vehicle trailer. The method determines a trailer angle of the vehicle trailer relative to a tractor, identifies at least one feature in an image of the trailer, determines a two-dimensional distance from the at least one feature to a predefined position on the image, and converts the two-dimensional distance to a three-dimensional distance based at least in part on the determined angle. The three-dimensional distance is a trailer detection parameter of the trailer.

  • Patent number: 12260562
    Abstract: A method for tracking a trailer end in an image using a controller includes receiving an image from at least one camera, identifying a trailer end in the image and tracking a motion of the trailer end through the image for a period of time using a controller. A motion model is generated based on the motion of the trailer end through the image using the controller. The controller responds to the trailer end exiting the image by maintaining motion of the trailer end per the motion model for a delay time period and establishing an estimated trailer end position dictated by the motion model at the end of the delay time period in response to the time period elapsing and the trailer end not being visible using the controller.
